Air separation plants
Combining engineering excellence with innovative process technologies to the benefit of our customers.

Positioned at the forefront of international plant engineering and a pioneer in air separation, Linde has been successfully engineering air separation plants for over a century and delivering these to a global customer base. In fact, we have already built more than 3,000 ASUs around the globe, including some of the world’s largest and most challenging multi-train plants.

Modular and customised designs support the full performance and purity spectrum, scaling from less than just a few hundred to 5,500 tpd, and supporting everything from low-purity flows to ultra-high-purity applications.

Winning combination

Our leadership in this area is built on a combination of innovative process technologies, state-of-the-art components and end-to-end engineering services extending from design and planning through to construction and operation.

Our plants utilise a low-temperature rectification process to produce oxygen, nitrogen and argon in gaseous or liquid form as well as other rare gases such as krypton, xenon, helium and neon.
